【摘要】 以长沙某一食堂建筑为例,对空调系统的冷热源系统的6种可能方案形式进行了全面的技术经济分析和比较,以初投资、运行费用、维护管理、可靠性、适用性、安全性等为评价指标,建立了评估决策模型,进行了多目标决策,进行优序,提出了适宜的系统方案。研究表明:多目标决策技术容易理解,计算简单,使用灵活,为空调冷热源方案选择提供了一种有效的定量分析方法,可辅助工程师对备选方案进行综合分析、评比并作出决策,增强了决策的客观性、科学性。更多还原

【Abstract】 Taking a dining hall of Changsha as an example,the six feasible schemes for air-conditioning system cooling/heating sources were compared by means of cost-effectiveness analysis.The evaluation model is established on the objectives of first investment,operation cost,maintainability and management,reliability,applicability and security to carry on multi-objective decisions and optimization array.The optimal system scheme is put forward.The result indicates that multi-objective optimization is easy to understand,simple to calculate and flexible to use,which provides an effective quantitative analysis method for the selection of the cooling/heating sources.It can assist engineers to analysis,evaluate alternative schemes synthetically and make a decision,which increases the objectivity and scientificity of the decision.更多还原
